upset of / because of

[Presther]

hello

I had an argument with s.o. whether "I am upset of you" is proper English grammar.
I know the terms: being upset with, about and because of. But is upset of ... an option too?

Thank you in advance

Hello Presther,
No, it isn't.
'upset over' is a possibility in limited contexts ("I was upset over the fact that the boss disagreed with me."), but usually the terms you have already mentioned are the common ones.
(Never 'upset of', though)
